Hello,
We have replaced 3 3600 controllers with 2 7210’s and old ap-65’s with ap-205’s. For the most part I just copied the relevant parts of the config to the new controllers. In another post I worked through sticky client issues that were related to outdated configuration settings, and things are much better now. I have also enabled HT and VHT on 20 MHz only for a and HT for g. Today I started digging around in the config again, specifically with a and g basic and transmit rates and doing some forum searches, and I think I need to make some improvements here too. I found a post that gave this link https://ase.arubanetworks.com/solutions/id/75 so I plugged in the information for one of the SSID’s and the recommendations are quite a bit different then what we have in our config, and I am hoping to get some input from the experts here if I should make these changes, and what I shouldn’t. We have a sparse deployment of AP’s (ap-105 and ap-205, never mixed in the same building) and we have 5 locations with a total of 155 AP’s. Buildings are medical clinics.
I only included parts of the recommended config that are different then what we are running.
Some things I noticed:
Min/max transmit are the same. Not what I have read anywhere.
We use the same arm profile for a and g. I think I should use a different profile for g with lesser transmit power.
The other arm setting are a lot different than ours. Should I use the recommended?
Should I remove 6 and 9 transmit rates? Seems like I should to improve performance.
